Panics = persist AFTER the tunings (for i386 certainly, and there are unsolved=20 reports about it on amd64 also) and are present even when driving kmem=20 size to the maximum. The tunings *can not solve the problems* currently, = they can only delay the time until they appear, which, by Murphy, often=20 means "sometime around midnight at Saturday". See also the possibility=20 of deadlocks in the ZIL, reported by some users. > Please report any further non-kmem panics you experience. I did, once to Pawel and once to the lists. Pawel couldn't help me and=20 nobody responded on the lists. Can you perform a MySQL read-write=20 benchmark on one of the 8-core machines with database on ZFS for about=20 an hour without pause? On a machine with 2 GB (or less) of RAM,=20 preferrably? I've seen problems on i386 but maybe they are also present=20 on amd64. --------------enigCE1F2BBCDE2C97088BADBDD9 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHgNy3ldnAQVacBcgRAqzHAKDfZWQg5+0b7chMA8z3yclmReYs6gCeJ3ir GBVQIzcpbjgFk9JfyTrb1m0= =1aOH -----END PGP SIGNATURE----- --------------enigCE1F2BBCDE2C97088BADBDD9--
